TIES, OF BRODHEAD,WISCONSIN IP'UDDLER FOR TANKS OF SEWAGE-D ISPOSAL PLANTS Applicationfiled August 8, 1929. Serial No. 384,415.

This invention relates to puddlers, and has bar 8 and the bar 10, and isconnected to the for one of its objects to provide a novel device ofthis character which shall be especially adapted to be used for thepurpose of churning and breaking up all solids accumulating in the tanksof sewage disposal plants. The invention has for a further object toprovide a puddler of the character stated which shall be strong, durableand highly eiiicient, which may be manufactured and sold at low cost,and which may be readily placed within and secured to a sewage tank.

With the foregoing and other objects in view, the nature of which willappear as the description proceeds, the invention consists in theconstruction, combination and arrangement of parts hereinafter fullydescribed and claimed, and illustrated in the accompanying drawings,wherein and partly in end elevation of the puddler;

Figure 2 is a sectional View taken on the Vertical planes indicated bythe line 2-2 of Figure 1;

Figure 3 is a sectional View taken on the horizontal planes indicated bythe line 33 of Figure 1, and i a Figure 4 is a sectional view taken onthe planes indicated by the line 4.4E of Figure 2.

The puddler comprises a frame 1, which by preference is of rectangularformation. The frame 1 consists of corner bars 2, vertical side bars 3,and upper and lower horizon tal side bars 4: and 5, respectively.

The bars 2 to 5 are of hollow and sectional formation, and the sectionsthereof are connected together by couplings 6.

The frame 1 is reinforced and strengthened by upper brace bars 7 and 8,which are connected to the upper frame bars 41 by the couplings 6 ofsuch bars, and by lower brace bars 9 and 10, which are connected to theframe bar 5 by the couplings 6 of such bars. The bars 7 and 9 arearranged at opposite sides of one vertical center of the frame, and

the bars 8 and 10 are arranged at the other vertical center of theframe. The bars 7 and 10 are of hollow and sectional formation, and thesections thereof are connected by couplings 11. A brace bar 12 extendsfrom the Figure 1 is a View partly in vertical section centers of saidbars by the central couplings of the same. A palr of tubular guides 13and a pair of similar guides 14; are arranged vertically Within theframe 1 at opposite sides 1 of the brace bars 8 and 10, and are securedto the brace bars 7 and 9 by certain couplings of such parts.

Paddles 15 and 16 are arranged horizontally within the lower portion'ofthe frame 1. The paddles 15 and 16 are of elongated rectangularformation and'each consists of side bars 17, end bars 18 and anintermediate cross bar 19. The bars 17 and 19 are of hollow andsectional formation and the sections aresecured together by couplings20. Each paddle 15 and 16 also comprises longitudinal- 1y extending bars21, which are arranged between the side bars 17 and are secured to theend bars 18. a

The paddles 15 and 16 are each provided with a pair of yokes 22, theyokes being ar ranged at the upper sides of the paddles'and at oppositesides of their transverse centers. The yokes 22 are made up from hollowbars tubes 13 and 14 and the guide rods 27 mount the paddles 15 and 16for vertical reciprocation within theframe 1.

A shaft 28, which may bedriven by an internal combustion engine,electric motor or the like and connected thereto by a worm or othersuitable gearing is journaled in bearings 29 secured to the upper endsof the frame bars 3 and 12, and is provided with cranks 30. Connectingrods 31 are engaged with the cranks 30 and with yokes 32, which aresimilar to the yokes 22 and are secured to the 9 frames 15 and 16 at thetransverse center of the same. The cranks 30 extend in oppositedirections from the shaft 28 in order to effect the simultaneousreciprocation of the paddles 1-5 and16inopposite directions.The'connecting rods 31 are engaged with the yokes nected to the paddlesand working in the 32 through the medium of sleeves 34, which guidetubes, and means for reciprocating the are pivotally connected to theyo-kes and to paddles.

which the connecting rods are adjustably In testimony whereof I hereuntoaffix my connected so as to permit the stroke of the paddles 15 to bevaried.

In practice, the puddler is arranged with- I in the tank of a sewagedisposal plant in a manner to position the lower ends of the frame bars2 and 3 upon the bottom of the tank, and the puddler is secured to thetank by elements engaging the bottom of the tank and passing throughattaching flanges 33 secured to the lower ends of said frame bars.

The rotation of the shaft 28 reciprocates the paddles 15 and 16 inopposite directions, with the result that all solids accumulating in thetank will be churned and broken up. The paddles 15 and 16 are heldagainst any tilting'movement while in operation by the guide tubes 13and 14 and guide rods 27, with the result that they will function attheir highest efiiciency at all times. The puddler may be made of anysize. The small size puddlers will embody two paddles and the largersize puddlers will embody three, four or more paddles, the number ofpaddles .to be employed depending upon the size of the signature.

While I have described the principle of the invention together with thestructure which I now consider the preferred embodiment thereof, it isto be understood that the structure shown is merely illustrative andthat suchrchanges may be made, when desired, as fall within the scope ofthe invention as claimed.

I claim comprising a frame, vertical guide tubes carried by the frame,elongated paddles arranged within the frame, yokes carried by thepaddles at opposite sides of their transverse centers and in alinementwith the guide tubes, guide rods fixed to the yokes and working in theguide tubes, yokes carried by the paddles at their transverse centers,ashaft horizontal bars and adapted to be arranged in the tank, pairs of'upper andlower horizontal brace bars. arranged within and secured to theframe at opposite sides of one vertical center thereof, upper and lowerhorizontal brace bars arranged within and secured to the frame at theother vertical arranged horizontally within the frame below the bracebars, vertical guide rods con 1.
